摘要： A vacuum channel field effect transistor includes a first insulator on a p-type semiconductor substrate, a gate electrode on the first insulator, a second insulator on the gate electrode, a drain electrode on the second insulator, and an n+ impurity diffusion layer in the surface of the p-type semiconductor substrate, the n+ impurity diffusion layer being in contact with a side wall including side faces of the first insulator, the gate electrode, and the second insulator. Application of predetermined voltages to the n+ impurity diffusion layer, the gate electrode, and the drain electrode causes charge carriers in the n+ impurity diffusion layer to travel through a vacuum or air faced by the side wall to the drain electrode, which can increase the source-drain current.

摘要： In an embodiment, a method includes forming a first diamond layer on a substrate and inducing a layer of graphene from the first diamond layer by heating the substrate and the first diamond layer. The method includes forming a second diamond layer on top of the layer of graphene and applying a mask to the second diamond layer. The mask includes a shape of a cathode, an anode, and one or more grids. The method further includes forming a two-dimensional cold cathode, a two-dimensional anode, and one or more two-dimensional grids by reactive-ion electron-beam etching. Each of the two-dimensional cold cathode, the two-dimensional anode, and the one or more two-dimensional grids includes a portion of the first diamond layer, the graphene layer, and the second diamond layer such that the graphene layer is positioned between the first diamond layer and the second diamond layer.

摘要： A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.
